high productivity (in terms of published output) is indeed correlated with high levels of collaboration [1-4,24,30,51,52,58,60].

A.J. Lotka. 1926, The frequency distribution of scientific productivity, Journal of the Washington Academy of Science 16, 317-323.

A pioneering insight into the productivity of sci- entists was provided by Lotka in 1926--an insight since confirmed by numerous others. He showed that the number of authors producing n papers is propor- tional to 1/n 2 [32]. Thus, the number of researchers producing just one paper in a given period of time is two orders of magnitude greater than the number of researchers producing 10 papers in the same time and four orders of magnitude greater that the number producing 100 papers. Lotka's findings have led some investigators to ask if prolific authors tend to collaborate more than less prolific authors.

Despite opinions to the contrary, these data suggest that there has been no apparent increase in overall productivity per active author over the last decade. Instead, authors are using their authorship potential more wisely by becoming more collaborative in the way they work, which is driving an apparent inflation in each author’s productivity as well as author bylines. Instead, the underlying driver of the volume increase in articles published is simply the introduction of new entrants/authors into the market. That is not surprising, as the total population of researchers globally continues to rise every year, and they become increasingly subject to the principles of "publish or perish": and so the cycle continues.

“Visit a web page, then select some text and annotate with comments or tags. You’ll see those annotations when you return to the page, and so will other Hypothesis users.”

Nothing is particularly hard if you divide it into small jobs.

“Don’t worry about things. Don’t push. Just do your work and you’ll survive. The important thing is to have a ball, to be joyful, to be loving and to be explosive. Out of that comes everything and you grow.”
